Warnings

Tools required

Parts

• Front wiper motor assembly × 1 — Use OEM specification
• Wiper linkage (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and set parking brake
2. Turn ignition off and remove key
3. Disconnect battery negative terminal and wait 2 minutes
4. Mark wiper blade rest positions on windshield with masking tape for reference
5. Ensure wipers are in parked position before beginning

Procedure

1. 1

   Remove wiper arms
   Lift the wiper arm away from windshield. Remove the protective cap from the wiper arm nut. Use a 13mm socket to remove the wiper arm retaining nut from each arm. Mark the position of each arm before removal. Use a rocking motion to pull each wiper arm off the splined shaft. Remove both driver and passenger side wiper arms.
2. 2

   Remove cowl top panel
   Open the hood. Locate and remove the plastic push-pin fasteners along the cowl panel using a trim removal tool. There are typically 8-10 fasteners across the cowl. Carefully lift the cowl panel weatherstrip. Remove the cowl top vent panel by lifting it up and away from the vehicle. Disconnect any washer hoses attached to the underside of the panel.
3. 3

   Access wiper motor area
   With the cowl panel removed, you will now have clear access to the wiper motor assembly and linkage. Identify the wiper motor located on the passenger side of the cowl area. Locate the wiper motor electrical connector with its locking tab.
4. 4

   Disconnect wiper motor electrical connector
   Press the locking tab on the wiper motor electrical connector and carefully pull the connector away from the motor. Inspect the connector terminals for corrosion or damage. Clean if necessary with electrical contact cleaner.
5. 5

   Remove wiper linkage from motor
   Locate the wiper linkage arm connection to the motor output shaft. Use a 10mm socket to remove the linkage retaining nut or clip. Carefully separate the linkage arm from the motor crank arm. Support the linkage to prevent it from falling or binding.
6. 6

   Remove wiper motor mounting bolts
   Locate the three wiper motor mounting bolts securing the motor to the cowl support bracket. Use a 10mm socket to remove all mounting bolts. Support the wiper motor as you remove the final bolt to prevent it from dropping.

   Module Mounting Bolts8 Nm (6 lb-ft)
7. 7

   Remove wiper motor assembly
   Carefully maneuver the wiper motor out of the cowl area. The motor may need to be rotated or angled to clear surrounding components. Inspect the mounting bracket and rubber isolators for wear or damage. Replace isolators if deteriorated.
8. 8

   Install new wiper motor
   Position the new wiper motor into the mounting location in the cowl area. Align the motor with the mounting holes on the support bracket. Ensure any rubber isolators are properly seated. Hand-start all three mounting bolts before tightening.
9. 9

   Torque wiper motor mounting bolts
   Using a torque wrench, tighten the wiper motor mounting bolts to specification in a star pattern to ensure even mounting pressure. Verify the motor sits flush against the mounting surface.

10. 10

    Reconnect wiper linkage
    Position the wiper linkage arm onto the motor output crank arm. Ensure the linkage is properly seated on the crank. Install and tighten the linkage retaining nut or clip. Verify the linkage moves freely without binding.
11. 11

    Reconnect electrical connector
    Push the wiper motor electrical connector firmly onto the motor until you hear or feel the locking tab engage. Gently tug on the connector to verify it is locked in place.
12. 12

    Reinstall cowl panel
    Reconnect any washer hoses to the cowl panel. Position the cowl top vent panel back into place, ensuring all alignment tabs are properly seated. Install all push-pin fasteners by pressing them firmly into their holes. Replace the cowl weatherstrip.
13. 13

    Reinstall wiper arms
    Reconnect the battery negative terminal. Turn ignition to ON position and activate wipers briefly to ensure motor cycles to park position, then turn off. Position each wiper arm onto its splined shaft according to your reference marks. Install the wiper arm retaining nuts and tighten to secure. Install protective caps over nuts. Verify arms are in correct parked position.

Reassembly

1. Ensure all electrical connectors are fully seated and locked
2. Verify wiper linkage moves freely through full range of motion
3. Check that all cowl panel fasteners are properly installed
4. Confirm wiper arms are aligned with original positions marked on windshield

Verification

• Turn ignition to ON position and test wiper operation at all speeds (intermittent, low, high)
• Verify wipers return to proper park position when turned off
• Test washer fluid spray function while wipers are operating
• Listen for any unusual noises during wiper operation
• Confirm wiper blades make proper contact with windshield throughout entire sweep
• Check for proper wiper blade synchronization and spacing
